SAN JUAN, Puerto Rico – Female interrogators tried to break Muslim detainees at the U.S. prison camp in Guantanamo Bay by sexual touching, wearing a miniskirt and thong underwear, and in one case smearing a Saudi man's face with fake menstrual blood, according to an insider's written account.

A draft manuscript obtained by The Associated Press is classified as secret pending a Pentagon review for a planned book that details ways the military used women as part of tougher physical and psychological interrogation tactics to get terror suspects to talk.

Former Army Sgt. Erik R. Saar, 29, confirmed the authenticity of nine draft pages the AP obtained. Saar worked as an Arabic translator at the U.S. camp in eastern Cuba from December 2002 to June 2003. At the time, it was under the command of Maj. Gen. Geoffrey Miller, who had a mandate to get better intelligence from prisoners, including alleged al-Qaeda members.

Saar said he witnessed about 20 interrogations and started noticing "disturbing" practices.

One female civilian contractor used a special outfit that included a miniskirt, thong underwear and a bra during late-night interrogations with prisoners, mostly Muslim men who consider it taboo to have close contact with women who aren't their wives.

Some Guantanamo prisoners who have been released say they were tormented by "prostitutes."

In another case, Saar wrote of a female military interrogator questioning an uncooperative 21-year-old Saudi detainee who allegedly had taken flying lessons in Arizona before the Sept. 11, 2001, terror attacks.

She wanted to "break him," Saar wrote, describing how she removed her uniform top to expose a tight-fitting T-shirt and began taunting the detainee, touching her breasts, rubbing them against the prisoner's back and commenting on his apparent erection.

The detainee spat in her face, the manuscript recounts.

The interrogator left the room to ask a Muslim linguist how she could break the prisoner's reliance on God. The linguist told her to tell the detainee that she was menstruating, touch him, then make sure to turn off the water in his cell so he couldn't wash.

Strict interpretation of Islamic law forbids physical contact with any menstruating women, who are considered unclean.

"The concept was to make the detainee feel that after talking to her he was unclean and was unable to go before his God in prayer and gain strength," says the draft, stamped "Secret."

The interrogator used ink from a red pen to fool the detainee, Saar wrote.

"She then started to place her hands in her pants as she walked behind the detainee," he wrote. "As she circled around him he could see that she was taking her hand out of her pants. When it became visible the detainee saw what appeared to be red blood on her hand. She said, 'Who sent you to Arizona?' He then glared at her with a piercing look of hatred.

"She then wiped the red ink on his face. He shouted at the top of his lungs, spat at her and lunged forward" – so fiercely that he broke loose from one ankle shackle.

"He began to cry like a baby," the draft says.

Events Saar described resemble two previous reports of abusive female interrogation tactics, although it wasn't possible to independently verify his account.
